lc fill 'whom it may cmicwiu:

lle it known that l,` linnn IVAN (inni-2N, it subject ol' the King of (ii-eat Britain, of the city oi' "loronto, county of York, Province ol'I Ontario, Canada, have invented certain new and useful lnipiovenients in Lighting- Fixtiires, of which the following is a sperilication. 1

My invention relates to improvements in lighting tinturea,y and one olijeot thereof is to provide a device ol the class described whereby a lixtnre may lie readily mounted for use, and li-mounted, iifitliout in any manner interli-,ring willi the permanent wiring in the nails or ceiling, and thus prevent damaging,r ol' the walls and ceiling, and the` wiringtherein i'ei'y commonly non` raueeil during these .iperutions. Another objet-t ol my invention is lo utilize a canopy or equivalent element as a coupling means whereby the weight ol'` the electric fixture Supported thereby is ultimately carried lay a suitable support carried by the Wall or ceiling, and without the necessity of having to use las'- tenin; I4 meansy to couple the canopy to itl support which would in any manner delace the walls or ceiling, thereby permitting the said canopy to be readily placed and replaced when the. 4fixture is mounted or de mounted. An embodiment within liiy inrention` and modifications thereof will be hereinafter more particularly set forth. and what Vl claim as new will la: pointed out in the claims toi-ming` part ol' this specification.

Figure l is a side elevation of the major portion ol in r fixture attached to portion of a wall or Ceiling liowii ilrsection; the canopy and a coupling for the fixture being shown in vertical central section; Fig. 2 is an elevation of the outer end of. the plug receptacle;- llig. 3 is a verllical cross section on the line 3-f` Fig. 2 with the canopy attached to the plug' recepllaele; Fig. 4 is a side elevation of the major portion of my fixture housed within an outlet box, which is attached to portion ot :iwall shown in section. a modified forni of canopy and coupling for the lixtiire being shown in vertical central eection` and Fig'. 5 is a part side elevation of a modified forin of plug receptacle, showing the saine mounted in an outlet box, shown in section. which is carried by portion of a wall or ceiling, a modified forni of canopy heilig also partly shown in section and adapted to he coupled directly to Said wall-box.

ln the iliawings, lilo rharaotern ol referenrv ri-lor to the saine parts.

I A certain essential element ot' niy lighting fixture, known as llie plug receptacle or conduit outlet, that is the receptacle which reeeires the plutl` wired [o the elec-trie lixturo7 when once placed in position, liefoiin-s; a permanent lixtnre.

From the following speriliealioin it will lie understood that my preferred Vtorni ot' plug receptacle or conduit millet max lie used without an outlet liox, though iii the broad coiu'eption ot' my inrention'ani' snitallle type of plug receptacle oi' ronduit outlet mai` lie used, and the saine may he; irl' ilesiri-d, mounted within amv snit-allie` will nl wall-box. l i l In the majority ol' lightingy fixtures or lixtin'e canopiesV with which l ain acquainted. the canopy itxelt is either direi-tlv attached to the wall or ceiling'. or permanently lorms part of a conduit outlet that. is directly' attailieil to the wall or ceiling, a .d in allisiich eases, urli .attaching means iiwessarilr iiijure4 the wall or ceiling-y partioularly when the said ranopies hare to be removed.

Ulivioiislr. since iny canopy not coupled hy sin-li a vlas`v ol t'asteniny means lo the Wall or ceiling, 1t can he readiliY niu'oiipled from its supportingr element without in any wise damaging the wall o1' ceiling; this ie a great advantage. not only when a tenant moves from one house to another. hut also for purposes of inspection,

All the essential parte oi.' my linlnre will he standardized so that the canopy assoc# ated with the lighting; tixture can he readilyv coupled lo the permanent ronduit outlet oai"- ried by the wall or ceiling, and as tlieplug i'ierinanently wired to the lioflltiiitr lixture will also be ol' standard size the same can. be readily inserted into` and removed from, the socket. carried by said eondnit outlet.

A is a preferred forni of conduit outlet, and the saine is made of suitable refractory material. rl"liis conduit outlet is coupled to the wall or ceiling B by any suitable means siieli. as screws L passing therethrough in the manner well-known in electrical art. The said conduit outlet is designed to be permanently attached to the wall or ceillrig, and it may be wired after any suitable manner; for this purpose I preferably provide theleondiiit outlet A with two holes l) and E y formed therein, and passed down through these holes aredwires F and G.

The wire F is passed through the inner end of the hole D and around a binding screw H and pinched between the head of this screw alnd the flange I of the socket J. A threaded nut 2 is embedded' in the conduit outlet A underneath portion of the flan I so as to receive the screw H. The wire is passed through a slot 3, formedin a metal plate 4, and is )inchcd between the head of the screw 5 which'-fscrews through the plate 4) and the said plate. The plate 4 is positioned as shown in Figs. 2 and 3 by means of a slot 6 formed in the conduit outlet A, and after this plate has been positioned the said slot may be closed by any suitable cement.

To permit the placing of the screw 5, the

outer end of the conduit outlet A is recessed as shown at 7.

Passing through portion of the flange I and through the flanges 8 carried by the socket J, are any suitable fastening means well known in the art, for instance screws 9 which pass through holes 10 (see dotted lines Fig. 3) formed in the conduit outlet A, and screw into nuts 11 mounted within pockets 12 formed in said conduit outlet, and which pockets are afterward sealed.

13 isi any suitable type of plug, and the same is supported by a socket J in any suitable manner, though the preferred manner of mounting the said plug in the said socket is as shown by means of the screw threads; but it must be understood that I have not confined myself to using this form of coupling.

The plug 1,3 is provided with any suitable contact plate 14, which makes contact with the screw 5 when said plug is fully coupled to the socket J. 15 and 16 are the-wires permanently carried b the plug 13, and these wires are passed t rough, or otherwise associated with, the pipe 17 of the electric li ht fixture.

@The path of the current will be understood by one skilled in the art as there is nothing particularly novel in the manner in which the electrical connections are made.

The referred form of conduit outlet A is provided exteriorly with a thread a, and engaging with this thread is a thread of the canopy 18. The lower portion of the canopy is reinforced as shown at 19, and

this reinforcement is threaded so that the threaded portion of the pipe 17 of the electric light fixture may he coupled thereto.

In order to couple the electric light lixturc to the conduit outlet A, since there is sufficient wire between the plu" 13 and the pipe 17, it will be understood that this plu may bc grasped by the hand and screwed into the socket J, and then the canopy 18 will be screwed on to the conduit outlet A so that the Weight of the electric fixture will be carried by the said canopy and confixture is carried by this canopy.

duit outlet, and f course ultimately by the wall or ceilin In Fig. 4, le conduit outlet A is shown as mounted in a wall-box 20, and the canopy 18 is shown as having threaded enga ement with said conduit outlet A. In order to cover the opening between the wallbox and the cano y 18', a truncated ring 21 is slipped on sai canopy and rests against the annular flange 22 thereof, and when this canopy is screwed home, the said truncated ring contacts with the wall or ceiling B and so hides the wa1l-box.

In this figure I show a modified form of coupler for coupling the pipe 17 of the electric light fixture to the canopy 18', so that the'canopy may be turned independently of said pipe 17. 23 is an internally-threaded bushing having a flared head 24, which is within said cano y nd rests against the lower end thereoi). The outer face of the bushing 23 is threaded and receives a jam nut 25. Of course the pipe 17 screws into the bushing 23, and by retracting the nut 25,

the cano y 18 may be independently turned. amming the nut 25 against the canop 18' locks the same avainst turning.

In ig. 5 I show a wallliox 26 as performing ne of'thc functions of the conduit outlet The inner wall of this wall-box is provided with a thread 27 with which engages the thread b of the canopy 18". It will of course be understood without further description that the electric li ht The p u 13 is of course coupled to the socket J, an this socket is! suitably carried by the plug receptacle A!" with which electrical connections are made. Jn this form of my invention, the receptacle A" has no thread.

It will he observed that the canopies 18 and 18' hohse the more or less slack of the wiring. bviously, very little slack need be. used with the form illustrated in Fig. 4, because the canopy 18 can be slid down the pipe 17 to permit the hand to readily grasp the pllg 13 to engage the Same with the socket ,and then afterward the canopy can he moved up into place and screwed over the conduit outlet A after which operation the jam nut 25 can be placed and screwed home.

The conduit outlet permanently carried by the wall or ceiling may 'consist of one part only such as the conduit outlet A shown in Fig. 1, or it may consist of two parts (a) the outlet or wall boxes 20 and 26, and (b) the conduit outlet A housed therein.

Although I state it is an object of my invention to support the fixture by means (for example the canopy 18) not attached to the wall or ceiling by attaching means that would deface the same, still I may use such means common in the art, such as screws or nails to attach the various suit'- able forms of canopy to the wall or ceiling los Where the plug 13 is coupled to the pipe 17 of the fixture by sufficient slack to per mit Said plug to be coupled to, or oncouplcd from` its associated socket, and Where .#:Lid

. pipe 17 is coupled' to mid canopy '18 o1' equivalentl element, to he within the claims of my invention.

The said slacli in the Wire is :t very importqnt feature of my invention in cornbination withthe plug 13 and its associated parts specically conceived, and any means claims.

What I claim. is, 1, A lighting fixture comprising e con duit outlet permanently carried by :i Wall or' ceiling; a Socket carried thereby and adapted for electrical` connections therewith; e fixture pipe; wires paesiug therethrough; a plug adaptedz-forelectrical connection with said wires and spaced apart from seid pipe by said wiring which provides the required slack, and designed to ne dctaclmbly coupled to said socket, and a coupling element in the forni of n lunopy thrmlgh which Suid pipe opens und to which the 5mmis coul'rled., :adapted to removably couple simili pipe and ixtures carried therein` directly to seid conduit. outlet.
